Fulham manager Martin Jol has expressed his anger at his side's 5-0 home defeat to Manchester United.
The result has left the Cottagers 11th in the Premier League table, five points off the relegation zone.
"I am angry and disappointed. They had eight attempts on goal and scored five goals. They played around us on the flanks and we did not defend well. Nani scored a header, which tells you all. We let ourselves down," Jol told BBC Sport.
"We improved and could have scored a few but it is easy when you are 3-0 down. They have a lot of quality but we were not aggressive enough. Conceding early is not good for your confidence. It was too easy for them. We have to pick ourselves up because there are a lot of teams on the same amount of points."
Jol's side make the short trip to London neighbours Chelsea in the league on Boxing Day.
